Title: Turbine blade wear protection system with multilayer shim
Inventor: HERZNER FREDERICK C
IPC: F01D5/28
Filed: 1991-11-28
Abstract: TURBINE BLADE WEAR PROTECTION SYSTEM         WITH MULTILAYER SHIM                   ABSTRACT OF THE DISCLOSURE A metallic reinforced shim is attached to the dovetail of turbine or compressor blades.  The shim reduces frictionally induced wear damage to the rotor.  In one form, a single ply shim reinforced with a metallic doubler has an anti-fretting layer deposited on the shim face contacting the dovetail slot pressure face, and a doubler layer fastened to the anti-fretting layer is the non-contacting regions to prevent slippage of the shim on the blade.  In another form, a multi-layer shim has two layers interposed between the blade dovetail and the disk dovetail slot, with the layers treated so that they do not readily slip relative to the titanium pieces, but do slip relative to each other.  The shim is also  reinforced with a metallic doubler.  Fretting is confined to the consumable shim, and therefore the disk dovetail slot and the mating blade dovetails are not subject to surface degradation with corresponding reduction in fatigue capability.

Title: Directional coupler type optical function element
Inventor: MAK HON-MING
IPC: G02F1/313
Filed: 1992-01-06
Abstract: ABSTRACT OF THE DISCLOSURE Provided is a directional coupler type optical function element with high extinction ratio, in which a junction of a 2-input/2-output directional coupler or 1-input/2-output directional coupler, formed of a semiconductor or dielectric, is formed by successively optically connecting, from the input side to the output side, a front-stage partial junction, front-stage partial junction with electrode, central partial junction, rear-stage partial junction with electrode, and rear-stage partial junction, each having a predetermined length.     The connection state at the front-stage partial junction and an incidence-side lead section optically connected thereto and the connection state at the rear-stage partial junction and an emergence-side lead section optically connected thereto cancel each other, thereby equivalently providing a symmetrical connection state and preventing the extinction ratio for a cross mode from lowering.  By forming the central partial junction with a proper length, moreover, the extinction ratio for a through mode can be kept high enough.  Thus, high extinction ratio characteristics can be enjoyed for either of the cross and through modes.

Inventor: SINDELAR ROBERT A
IPC: E01C19/10
Filed: 1992-01-08
Abstract: A blacktop plant has a rotatable cylindrical mixing drum.  The drum is disposed within a chamber which is divided into two chambers by a baffle through which the drum penetrates.  The forward section of the heating chamber preheats the material which is fed into the drum for heating and recovers latent heat from the water vapor in the heating chamber exhaust.  The second chamber has a multiplicity of burners mounted beneath the drum and aligned with the drum axis.  Each heater is partially baffled from adjacent heaters by zonal baffles.  The heaters are rotatively mounted to a frame upon which the heating chamber and drum are mounted and may be rotated to change the angle with which the burner flame impinges upon the drum.  Quadrant plates partition the drum along its axis to form the drum into four equal quadrants.  The quadrant plates have drop slots which allow the material to pass from one quadrant to another.  The material in the drum is heated in counterflow by the combustion gases from the burners in the heating section of the chamber.  The blacktop plant has flat stack scrubber units disposed along the sides of the chamber for cleaning the exhaust gases with counterflowing spray water.  The plant is adapted for mounting on a trailer for movement over the surface to be paved.  The chamber is insulated and allows the use of microwave energy for heating the asphalt and sound energy for cleaning the mixing drum.

Title: Liquid clarification by effecting cohesion of soilds
Inventor: REICHNER THOMAS W
IPC: B01D21/00
Filed: 1992-03-03
Abstract: ABSTRACT     Contaminated  liquid  or  sludge  clarification  is accomplished  by  the  use  of a  basic  one  or  a series  of operatively  connected  and  vertically  extending  units  or devices of the invention, each of which employs a hose that is spiraled around a cylindrical container wall whose upper end is  open to an overflow weir  from which recovery of  lower specific gravity  clarified liquid is effected and whose lower end is open and connected to a cone or funnel-shaped wall that defines a receiving and delivering chamber for separated-out heavier     specific     gravity     contaminating     liquid, sediment,  viscous or thickened material.   The hose of the basic  unit  is  adapted  at  its  upper  end  to  receive  the contaminated  liquid,  sludge  or  the  like  and  any  suitable chemical  flocculant,  precipitant,  or  coagulant,  such  as  a polyelectrolyte,  that  may  be  injected  or  added  to  the contaminated liquid before it is introduced therein.  The hose is  adapted  to thoroughly  mix the heavier  specific gravity material  content with the coagulant as the   liquid charge moves downwardly in a somewhat slowly swirling path therein.          A nozzle is connected to the lower end and along the inside of a lower end portion of the cylindrical wall to deliver its contents  in  a  substantially  vertically  laminated  relation within  the  container  above  and  adjacent  to  an  upper  end portion of the cone-shaped wall. When, as contemplated, two or more of the units or devices are to be used in series progression to work in a vertically extending series of sludge feed-in operating units, the lower end of the cone-shaped wall of each  upper unit is provided at its lower end with delivery pipe  or  tubing  that  extends  downwardly  along  the  central vertical  extent  of  the  next  lower  unit  to  discharge  its heavier specific gravity or contaminate   material through a pinch valve or the like into the  cone of the next lower unit to combine with the contaminate material  separated out  or processed in the  next lower unit, and then with such material to  be  discharged  therefrom.    When  additional  units  are connected in series delivery progression, then the "down" or delivery  pipe  of  each  succeeding  lower  unit  is  enlarged progressively to take care of and also deliver the  amount of greater specific gravity  material that is being separated-out and collected by an uppermost unit  of the series.

Title: Hydrostatic radial pocket bearing for a servo cylinder
Inventor: EIGENBROD KARL-HEINZ
IPC: F16C32/06
Filed: 1992-04-24
Abstract: A B S T R A C T     Hydrostatic radial pocket bearing for a servo cylinder A hydrostatic radial  pocket bearing for a servo cylinder is des-cribed,  particularly for a high performance  testing cylinder,  of the kind as used, for example, in test rig or simulation technology.          The radial pocket bearing is suitable for the highly precise regu-lation of the piston and for receiving large transverse forces acting on the piston rod.  An even number of bearing pockets is uniformly distributed over the  bearing periphery and  fed  from  a  source  of pressure fluid by way of associated preliminary throttles connected to pressure supply conduits and by way of an associated connecting conduit.   The preliminary throttles are formed by  the bearing gap between a supply orifice and at least one outlet groove in an oppo-site bearing pocket,  the bearing pocket being in the form of a re-entrant depression  either in  the fixed or  in  the  moving  bearing portion.   To reduce loss energy caused by leakage and at the same time  increase  the force  carrying  capacity  of  the  bearing, the pressure drop of  the  pressure  fluid  flow  axially  away  from  the bearing pocket is different on both sides.
